Hexavalent chrome, also known as chromium (VI), has been widely used in various industries for its exceptional corrosion resistance and durability. However, its toxic nature poses significant risks to human health and the environment. To address these concerns, High-Velocity Oxygen Fuel (HVOF) coatings technology has emerged as a REACH-compliant alternative, offering performance that exceeds customer requirements while minimising environmental impacts.
HVOF: The REACH-compliant solution
HVOF is an advanced thermal spray coating technique that utilises a high-speed stream of oxygen and fuel gas to propel molten particles onto a substrate surface. This process creates a dense, tightly bonded coating with excellent adhesion and high-quality mechanical properties. Importantly, HVOF coatings can provide a viable substitute for hexavalent chrome in a wide range of applications, including aerospace, automotive, and other manufacturing industries.
One of the key advantages of HVOF coatings is their ability to exceed customer requirements. HVOF coatings offer exceptional hardness, wear resistance, and corrosion protection, making them suitable for demanding applications. This makes it possible to replace hexavalent chrome with HVOF coatings without compromising the performance and functionality of the coated parts or components.
The Registration, Evaluation, Authorisation, and Restriction of Chemicals (REACH) regulation in the European Union aims to protect human health and the environment by ensuring the safe use of chemicals. Hexavalent chrome is subject to strict restrictions under REACH due to its toxicity. HVOF coatings, on the other hand, are a compliant alternative, as they do not contain hexavalent chrome or any other restricted substances. By adopting HVOF technology, companies can adhere to REACH regulations and promote a safer working environment.
The adoption of HVOF coatings offers several environmental benefits over hexavalent chrome:
- Reduced health risks: Hexavalent chrome poses significant health risks, including respiratory problems and potential carcinogenic effects. By eliminating the use of hexavalent chrome, HVOF coatings reduce workers’ exposure to toxic substances, ensuring a safer workplace.
- Reduced environmental contamination: Hexavalent chrome runoff from industrial processes can contaminate soil and water, posing a threat to ecosystems. HVOF coatings are environmentally friendly, as they do not release hazardous substances. This helps protect water resources and preserves ecological balance.
- Extended equipment lifespan: HVOF coatings provide superior protection against corrosion and wear, extending the lifespan of coated equipment and components. This reduces the need for frequent replacement and associated resource consumption, further promoting environmental sustainability.
HVOF coatings offer a REACH-compliant alternative to hexavalent chrome, mitigating health risks and environmental concerns associated with its use. With performance that exceeds customer requirements while extending component lifetime and a range of ecological benefits, HVOF technology is becoming increasingly popular in various industries as a viable alternative. By adopting HVOF coatings instead of hexavalent chrome, companies can enhance workplace safety, reduce environmental contamination, and contribute to a more sustainable future.
